11、保护就越显重要，相应地对防雷保护提出了更高的要求。本文对于高层建筑物的防雷保护措施做了较为仔细的分析。关键词：配电系统 负荷计算 防雷设计 照明IResidential quarters for the distribution designAbstract: In order to improve the reliability of power distribution system of high building,choice capacity of power distribution device rightly,it is necessary calculate charge r

12、ightly,the author analyses and investigates relative question with charge calculation,expatiates particularly capacity choice of important equipment,puts forward these measure being used to improve the reliability of power distribution system,makes charge calculation combination to project example,t

13、he result shows that these means is right and reasonable,these means can guide project practice. High building is easy suffered from lightning stroke,in case being suffered lightning stroke,it should bring huge losing,lightning protection system of common building can not protect electronic device,o

14、n the contrary,it may introduce lightning therefore high buildings lightning protection is more important.The author analyses and research these question of over voltage and of lightning stroke,puts forward these means of lightning protection of in high building.Keywords: power distribution system load calculation synthetic ightning protection IlluminationI1 前言本次设计的题目是某住宅小区电气系统设计。通过具体的实例工程设计，初步掌握高层建筑供配电系统设计的基本方法,更好的
